The Rolex Sea-Dweller 4000 (Ref. 16600) is a legendary dive watch engineered for professional deep-sea divers. Crafted from Rolex’s 904L Oystersteel, the 40mm case offers unmatched corrosion resistance and strength. A unidirectional rotating bezel with a 60-minute graduated scale ensures precise dive timing, while the scratch-resistant sapphire crystal provides superior durability.

Designed for extreme underwater missions, the Sea-Dweller 16600 features an impressive 4,000ft (1,220m) water resistance, supported by a Triplock screw-down crown and a helium escape valve that regulates internal pressure during saturation dives. The black dial is fitted with luminous hour markers and Mercedes hands, ensuring legibility in low-light conditions.

At its core, the Rolex Caliber 3135 automatic movement delivers COSC-certified precision, a 48-hour power reserve, and exceptional reliability. The watch is paired with a solid-link Oyster bracelet featuring the Fliplock extension system, allowing divers to wear it comfortably over wetsuits.

A true icon in Rolex’s professional collection, the Sea-Dweller 16600 is the ultimate blend of heritage, functionality, and innovation, making it a coveted choice for both divers and collectors.
